Left-Hand Undermount Runner For Compact Frameless Drawers

The Hettich Actro 5D is a left-hand cabinet runner in the Actro 5D undermount series, sized for 300mm drawer boxes and rated 88 lb per pair. It delivers full extension with integrated soft-close and installs in frameless cabinet construction.

Key Features

• Left-hand orientation — a single handed runner; pair with the matching right-hand member to complete one drawer installation.
• 300mm nominal length — sized for compact drawer boxes built to the 300mm nominal specification.
• Full extension — brings the entire drawer out to the cabinet face so the full interior is accessible.
• Integrated soft-close — damped closing settles the drawer silently without a separate add-on damper.
• 88 lb load rating per pair — handles everyday kitchen and furniture drawer loads with headroom to spare.
• Ball bearing runner — steel ball bearings provide smooth, consistent travel through years of cycles.

Where the 300mm Runner Earns Its Place

A 300mm undermount runner is the right choice for shallower drawers: spice pull-outs, cutlery inserts, bathroom vanity drawers, and bedroom nightstand boxes that do not need the depth of a standard kitchen run. Full extension matters here — on a short drawer, losing the back two inches to a 3/4-extension slide means losing a meaningful portion of the usable space. The Actro 5D brings the whole box clear of the cabinet, which is exactly what a shallow drawer needs to be practical.

The 88 lb pair rating covers the loaded weight of any realistic compact drawer application. This runner is a single left-hand cabinet member; order one right-hand runner of the same series and length, plus the correct drawer members and front locking devices, to complete the installation.

Construction and Finish

The runner is steel with a zinc finish — the standard corrosion-resistant finish for an indoor undermount component that lives inside a cabinet and is never seen in use. Ball bearings run in formed steel raceways, carrying the load smoothly across the full travel without racking. The Actro 5D series supports 5D adjustment through its front locking devices, allowing the installed drawer front to be trued in five directions after the box is hung.

Drawer side thickness compatibility runs from 1/2 inch to 5/8 inch (maximum 5/8 inch), so the runner suits both thinner and standard drawer box sides within that range. The box must be built to the Actro 5D specification, including the correct width formula, rear notch, and any locking-device drilling, before installation.

The Right Fit for Frameless Production Work

Actro 5D runners mount directly to the interior side panel of a frameless cabinet — the 32mm system grid makes placement consistent across a production run. For shops building high-volume frameless cabinetry in bath, bedroom, or compact kitchen configurations, the 300mm length fills the gap between novelty-shallow trays and the more common 400–500mm kitchen depths. Designers specifying undermount hardware for tight vanity or nightstand interiors will find the 300mm Actro 5D handles the constraint without forcing a compromise on extension or soft-close performance.

Start With the Right Runner

A 300mm drawer built on Actro 5D runners gets full access and a soft, silent close in a compact footprint — the details that separate a finished cabinet from a functional one.
